HEATER.

Application filed February hiv invention relates to a device tor heating solid, liquid, or gaseous matter, by the transmission ot heat from a heated gas or liquid or" any nature. It relates more par ticularly to a device `for heating a room by the transmission to the air ot' the room ot heatI from the gases of combustion ofany suitable material, more especially 'from the combustion of gas.

An object of my invention is to provide a heater' having a series ol thin, hollow partitions or walls placed Close togetL er, open at the bottom and top for the circulation of air, and a source of heat at one edge of the assembled hollow partitions, and an exit for the products or combustion at the. oppo site edge. A further obiect is to torce the ilow of the products ot combustion over the surfaces of the hollowpartitions by placing the exit for such products at a low position in the side opposite the source otheat.

In my specific construction, I have a boxlike sheet metal structure supported on legs with a plurality of thin` hollow partitions placed close together with their outside edges separated from the end walls ot the structure. These partitions are open at the bottom, drawing air from the floor ot the room and have a hood receiving the heated air from the top, whence it is discharged into the room. At one end of the structure, pref erably along` the bottom end edges of the hollow partitions I place a gas burner having a suitable valve, and air inlet toprovide tor the combustion. At the opposite end ot the structure, and the opposite edges of the hollow partitions, the exit 'for the products of combustion is placed low down in order to torce the flame and burnt gases to take a longer path of travel over the surface ot the hollow partitions. A stove pipe, or other line, may be connected to the gas exit outlet.

I attain these object-.s by the device illustrated in the accompanying drawings in which Fig. 1 is a vertical section taken lengthwise, Fig. 2 is a horizontal section, and Fig. 3 is an end view of a device embodying the principles of my invention. Figure l is an enlarged detail view.

It is understood that the drawings are intended for purpose of illustration only,l

and that various changes maybe made in the siz-e, shape, proportions, and minor ldetails without departing from the spiritl or ,sacrificing any of the advantages of the in- 8', 1923. Serial No.,617,87l.

vent-ion as claimed. I also desire it to be understood; that the principles of my invention may be applied to a number ot' uses and that I do not wish to be lin ited in my Aclaims to the particular use shown, where I E?, extending across the bottom ot one end,

and a vent opening and pipe, 12, equidistant from the sides atl the -other end slight-ly higher than the lcvelot the top of the flame of the burner,

rlhe vent pipe, 12, is shown fastened to the box, 1, by rivets, 13. The burner is shown equipped with a mixer, 3, a valve, 4;, and a connection for attachment to a gas line, 5. The burner enters the rectangular box, 1, through suitable openings and is held in position by suitable fastening.

Should the box, l, have a top and a bottom with nothingl inside ot it, in operation the entire box, 1, would be filled with the hot gases 0lz combustion enroute to the flue from the burner. The drawings however show the volume ot' this box broken up by the spacing ot a plurality ot rectangular air lines, 9, which connect the top and bottomV of the box, 1, and are openat the top and bottom so that the air which they contain is free to circulate upward into the room upon being heated.

Between each of these air tlues, 9, is a space, 8, through which the hot gases of combustion may pass on their way from the burner, 2, to the vent pipe, l2. The spaces, 8, are closed at the top and bottom to pre vent the hot gases ot combustion entering the air in the room, and the air flues, 9, are closed at the ends next to the burner and iue to prevent the combustion gases entering the air lines, 9.

The top and bottom of the box, 1, are not shown aliiXed to the box,r1, but are shown atliXed to the air lues, 9, in such a manner that it desired, the top and bottom together with the air fines, 9, may be removed from the box, 1, by being lifted upward. rIhe junction of the top and bottom ot the box. 1, with the sides of the box, l, is made tight against the escape ot the gases of combustion tlf) by the top. and bottom resting upon lips, 19, and, 20, respectively, said lips being a part of the sides and ends of lthe box, l. The weight of the air fines tends to seal this junction sufficiently to prev-ent escape of gases of A combustion into the room. The top and bottom may be liXed to the box, l, with a sealed joining but I prefer them removable as shown.

A hood, let, may be usedto direct the current of heated air in an effective direction.

The box, l, and air flues, 9, may be made of any suitable material, but I prefer them made of sheet iron.

Any suitable burner may be used, but I prefer an elongated burner for purpose of economy of space and equal distribution of the gases of combustion. Any 1suitable mixer, valve, and connection may be used with the burner.

Any suitable means may be used for fastening together the various parts, but I prefer the junctions welded.

The box, l, majT be supported by metal legs, l5, bolted to the boX.

It can easily be seen that in the application of the principles of the heater to a gas heater for heating a room, a device has been provided which will not discharge any harmful burnt or unburnt gas into the room, and yet will secure maximum heating from the gas consumed. It will occupy minimum space in proportion to its amount of heating surface. It may easily be dissembled for cleaning' or repairing. It provides means for deflecting the heated air in an effective direction, and it provides a heater for a house or room which will be healthful and economical in its use. Moreover it is of such construction that it will neither be difhcult nor costly to manufacture'.

It will be apparent from the above description in connection with the drawing that the products of combustion from the burner follow along each side of each hollow partition. As these partitions are quite thin Vand the space between them is narrow the products of combustion are brought into contact with al large heating surface and transmit their heat to thin columns of air rising through the hollow partitions. Placing the vent pipe l2 low down on the end of the rectangular metal box causes the burnt gases to ascend and then descend, in other fords, have a somewhat circulating movement.

I claim l. In a h-eater of the character described, a` rectangular container having a burner arranged along the lower front edge thereof, a flue in the rear Wall and parallel partitions arranged longitudinally of the container and stopping short of the front and rear walls thereof to form flat chambers adjacent the said front and rear walls, alternate sets of adjacent partit-ions being joined at the front and rear ends and the other sets being'joined at the top and bottom to cause fiat columns of air to rise between similar flat columns of heated gases traveling from the front to the rear.

2. In a hea-ter of the character described, a rectangular container having a burner arranged along the lower front edge thereof, a flue in the rear wall and parallel partitions arranged longitudinally of the container and stopping short of the front and rear walls thereof to form Hat chambers adjacent the said front and rear walls, alterna-te sets' of adjacent partitions bein@ joined at the front and rear ends and the other sets being joined at the top and bottom to cause flat columns of air to rise between similar flat columns of heated gases traveling from the front to the rear with a hood on top of the container arranged to deflect the rising columns laterally and to discharge the same downwardly.

3. In a heater of the character described, a rectangular container having a burner arranged along the lower front edge thereof, a tine in the rear wall and parallel partitions arranged longitudinally of the container and stopping short of the front and rear walls thereof to form flat chambers adjacent the said front and rear walls, alternate sets of adjacent partitions being joined at the front and rear ends and the other sets being joined at the top and bottom to cause flatcolumns of air to rise between similar flat columns of heated gases traveling from the front to the rear, the flue being arranged slightly higher than the burner.
